The blades of 24-layer "Damascus steel" (Suminagashi), laminated with Blue Paper Steel (approx. 61 HRC), have outstanding endurance, even on the hardest woods. With its integral design, the hefty handle of Japanese red oak, with a strong heavy-duty ferrule, transmits the highest impacts to the blade. The blades are sharpened and ready for use, not angled and have a plane back (not hollow-ground). Set of 6 in kiri-wood case (6/12/19/25/32/38 mm).
